Discharge analysis of SrO- and SrCaO-cathode PDP operated at lower voltage

抄録

  We present the measurement on SrO- and SrCaO-cathode PDP operated at lower voltage. SrO- and SrCaO-cathode PDP attain high luminous efficacy at low voltage, where the breakdown voltage is 30% lower than that of the ordinal MgO-cathode PDP. Emission measurements clearly demonstrate that the SrO- and SrCaO-cathode PDP have a weak discharge with small current flow and low electron energy, which is appropriate for high luminous efficacy of PDP. Also, the direct measurement of VUV radiation from a PDP small cell shows that increasing Xe gas pressure leads to a drastic increase in excimer radiation (172 nm) from Xe molecule, which also considerably contributes to the high luminous efficacy of PDP.
